 巴音郭楞职业技术学院 高职生毕业设计（论文） 设计（论文）题目： 基于单片机的电子显示屏设计 系 别： 电子信息工程学院 专 业 (方 向)： 电子信息工程技术 2012 年 5 月 20 日 摘 要 LED显示屏是利用发光二极管点阵模块或像素单元组成的大面积显示屏幕。由于它具有可靠性高、使用寿命长、性能价格比高、使用成本低、环境适应能力强等特点，广泛应用于金融市场、医院、高速公路等公共场所的信息显示和广告宣传。LED显示技术是将光电、计算机以及控制等技术综合一体的现代新技术。LED显示屏系统主要由显示屏、显示屏控制器以及完成文字录入和显示模式控制的计算机三个部分组成。该系统既可以显示中文、英文，也可显示图形符号或用户指定的特殊图形符号。本课题研究的主要对象是基于ARM嵌入式微处理器的大屏幕LED显示系统的软、硬件组成。采用基于ARM核的新一代32位嵌入式RISC微处理器组成前级驱动电路，PC机用于后级管理和控制，方便地组成由多块大屏幕LED显示器构成的显示系统。 32位ARM微处理器ABSTRACT The LED screen is a large area screen that consist of light-emitting diode tube dot matrix model or pixel unit. Because of high reliability, long life, high cost performance, low cost in using and powerful environmental adaptability ect., the LED screen is widely applied to information display and advertising of financial markets, hospitals, highways and other public places. The LED displaying technology is a new and modern technology which integrate optoelectronics, computers and control. LED display system mainly consists of displays, display controllers, and computer which complete the mode control of text entry and display. The system can display not only Chinese, English, but also the graphic symbol or special graphic symbols specified by the user. The study object of the topic is the integration of software and hardware. The integration is a wide screen display system which mainly based on ARM embedded microprocessor. Taking a new generation 32-bit embedded RISC microprocessor which is based on ARM kernel to make up before-level driving circuit. Then use a PC deal with the after-level management and control. To do like this make it convenient to make up the display system which is consist of many packs of wide LED screens. ［Keywords］ LED; Data transmission; 32-bit ARM microprocessor 目 录 第1章 LED显示屏的基本概述 1 1.1 LED显示屏的发展历程 1 1.2 LED显示屏市场应用领域 2 1.3 LED显示屏的分类 2 第2章 LED显示屏的性质及原理 3 2.1 LED显示屏的分类 3 2.1
